GREAT PYRAMID SECRET REVEALED

Scientists in Egypt announced in November that they had detected a previously unknown “void” inside the Great Pyramid of Giza. It was the first time since the 19th century that a major interior structure was found within the 4,500-year-old pyramid, which is located along the Nile River a few miles from Cairo, Egypt.

To make the discovery, the archaeologists used special detectors that “see” high-energy subatomic particles called muons. The same technology may make it possible to find hidden features in other archaeological features.
